Write an equation in Point-Slope Form for the given information. m=4/5;(2,0)

Mathematics

1 answer:

Nitella [24]2 years ago

4 0

Answer:

y-0 = 4/5(x-2)

Explanation:

0 is the y point so it goes in the y-y1 spot. The m or the slope goes into the m spot by the parenthesis. The 2 goes into the spot of the m-m1. One thing that is important is that when plugging in the point into the equation is to always put in the inverse. So if 3 was the y point, the equation would be y-3, if it was a negative point it would be, y + 3.

A polynomial with rational coefficients has roots 5 and -6i. (The i is an imaginary number not variable). What is the polynomial

mars1129 [50]

Answer:

The answer is { $x^{3}$ -(5) $x^{2}$ (36)× $x$ -(180)

Step-by-step explanation:

A polynomial with rational coefficients has roots 5 and -6i (There i is the

imaginary number not variable )

As we knew that imaginary no comes in pair . This means that if -6i is

one root then the other root will be 6i

So if we assume the lowest polynomial that is possible is given as

{ $x^{3}$ -(sum of all roots) $x^{2}$ +(roots taken two at a time)

$x$ -(product of all roots)

{ $x^{3}$ -(5+6i+(-6i)) $x^{2}$ +(5×6i +5×(-6i) +6i×(-6i))

$x$ -(5×6i×(-6i))

$i^2$ = -1

{ $x^{3}$ -(5) $x^{2}$ (36)× $x$ -(180)

The general case we assume that the three previous roots and rest roots

a4,a5,a6 ...............an

$x^n$ -(sum of all roots)× $x^{n-1}$ +(roots taken two at a

time) × $x^{n-2}$ - .......................................... (product of all roots)

Expression for the quotient of b divided by the difference of two minus 3

uysha [10]

Answer:

The required expression is

$\frac{b}{2 - 3} = - b$

Step-by-step explanation:

Difference of two minus three = 2-3

Quotient of b divided by the difference of two minus three is

$\frac{b}{2-3} = \frac{b}{-1} = - b$

Therefore, the required expression is

$\frac{b}{2-3} \ \ \ \ \ \ \ \ or \ \ \ \ \ \ \ \ - b$

Write down all elements of ({9, 10, 11} ∩ {10, 11, 12, 13}) ∪ {14, 15}. (enter your answer in set notation.)

iren [92.7K]

What we have so far:
Let set A = {9, 10, 11}
Let set B = {10, 11, 12, 13}
Let set C = A∩B. This means: the intersection of A & B.
Let set D = {14, 15}
Let set Universal = C∪D. This means: the union of C & D where C is the intersection of A & B.

Solution:
Let us first solve for set C.
C = A∩B
C = {9, 10, 11} ∩ {10, 11, 12, 13}
C = {10, 11} <--- New value for set C

Let us now solve for set Universal.
Universal = C∪D
Unviversal = {10, 11} ∪ {14, 15}
∴ Universal = {10, 11, 14, 15} <--- What we are looking for.

Therefore, the answer is Universal = {10, 11, 14, 15}.
